Abstract
A network cable includes first and second connectors and corresponding sets of connector pins and signal wires. A coupling piece controls the routing between the first set of signal wires and the second set of signal wires. The coupling piece includes at least two configuration settings where each configuration setting actuates a corresponding routing between the two sets of signal wires. The first configuration setting may actuate a passthrough configuration where each first connector pin is connected to a like numbered second connector pin. The second configuration may actuate a crossover configuration in which at least some of the first connector pins are connected to like numbered second connector pins and at least some of the first connector pins are connected to un-like numbered second connector pins. The coupling piece may include a cylindrical outer piece that rotates around an inner piece to actuate the various configuration settings.
Description
- 1. Field of the Present Invention
- The present invention generally relates to the field of electronic signal cables and more particularly to cables used to connect one or more data processing systems in a data processing network.
- 2. History of Related Art
- Wired computer networks typically include one or more data processing systems that are connected by some form of cabling. Among the most pervasive types of cable are the various types of Ethernet cables. Ethernet refers to network hardware and protocols that comply with IEEE 802.3. Ethernet cables provide the physical medium that connects systems in an Ethernet network. The most common Ethernet networks today are 10 Megabit/second and 100 Megabit/second networks. Many of these networks employ twisted pair wire cabling as the most cost effective means of connecting systems in high data-rate networks.
- Referring to FIG. 1A and FIG. 1B, two of the most commonly encountered methods of connecting multiple systems in a LAN are depicted. In FIG. 1A, a “direct connect”
network 100 includes a firstdata processing system 102, a seconddata processing system 104, and acable 106 connected between them.Data processing systems - Cable106 is typically a
CAT 5 twisted pair cable that includes 8 wires (4 pairs). In an Ethernet embodiment, these 8 wires include plus and minus transmit wires (T+, T−), plus and minus receive wires (R+, R−), and four power signals (GND, VDD, etc.). In adirect connect network 100, it is necessary to connect the receive wires of one device to the transmit wires of the other device and vice versa. Thus, in FIG. 1A, the R+ connection ofsystem 102 is connected to the T+ connection ofsystem 104, the R− connection ofsystem 102 is connected to the T− connection ofsystem 104 and so forth. This connection configuration is commonly referred to as a “crossover” connection and thecable 106 that implements the crossover connection is referred to as a crossover cable. - In the
network 110 as depicted in FIG. 1B, multiple data processing systems, two of which are represented bysystems ports hub 120 viacables 116 and 118 respectively. The hub configuration ofnetwork 110 beneficially enables multiple systems to connect to a common hardware device to create a LAN that includes several systems. In an Ethernet implementation ofnetwork 110,hub 120 is typically configured to connect tosystems connection ports system 112 is connected to the T+ signal ofport 122 onhub 120. - It will be appreciated that it may be desirable to alter network configurations from time to time for any of a variety of reasons. Thus, for example, a particular system or pair of systems may at one time be part of a direct connect network such as
network 100 while, at other times, they may comprise a portion of ahub configuration 110. It would be desirable to implement a cable that could accommodate either configuration without significantly increasing the cost or complexity of the cable and without an appreciable loss of reliability. - The problems identified above are in large part addressed by a network cable according to the present invention. The cable includes a set of signal wires connected between a pair of connectors and has at least two configuration settings. In a first configuration setting, the pass-through configuration setting, the cable's signal wires are connected between like connector pins such that, for example, pin1 of a first connector is connected to pin 1 of a second connector,
pin 2 of the first connector is connected topin 2 of the second connector and so forth. In a second configuration, the crossover configuration, at least a subset of the signal wires connect unlike connector pins such that for example, pin 1 of the first connector may be connected topin 3 of the second connector. - The cable is preferably transitionable from the first cable setting to the second cable setting by hand. In one embodiment, the cable includes a substantially cylindrical coupling piece intermediate between the two connectors. The coupling piece receives signal wires from the two connectors and provides a mechanism for coupling the signal wires from the first connector to the signal wires from the second connector. In one embodiment, the cylindrical coupling piece includes an annular outer shell that encloses an inner cylindrical piece. The outer shell may be rotated around the inner piece from a first position to a second position. When in the first position, the cylindrical coupling piece connects the signal wires of the two connectors in a first configuration while, in the second configuration, the coupling piece connects the signal wires in a second configuration.
- In other embodiments, the cable may include alternative forms of coupling pieces. In one embodiment, the coupling piece includes a hand settable switch. The position of the switch dictates the coupling configuration such that a first position of the switch enables a first coupling configuration, a second position of the switch enables a second coupling configuration, and so forth. Another embodiment of the coupling piece includes a mechanism that is configured to retract the cable ends when not in use.

- The present invention generally encompasses cables used in computer networks and more specifically cables that incorporate multiple configuration settings. These configurable cables include some form of mechanism by which a user can alter the cable's configuration from a first configuration to a second configuration. As used in the context of this disclosure, a cable configuration refers to the specific manner in which the cable connects two (or more) devices. In an embodiment suitable for use in the widely installed base of Ethernet systems, for example, the configurable cable according to the present invention includes a pass-through configuration in which the cable connects like connector pins (pin1 to pin 1,
pin 2 to pin 2, etc.) and a crossover configuration in which the cable connects at least some pins of its first connector to unlike pins of its second connector (e.g., pin 1 to pin 3). In one specific implementation according to this embodiment, the pass-through configuration is suitable for connecting a data processing system to a hub or other similar network connection device while the crossover configuration is suitable for directly connecting two data processing systems to each other in an Ethernet configuration. - Turning now to the drawings, FIGS. 2A and 3A illustrate a first embodiment of a
data processing network 200 incorporating aconfigurable cable 210 according to the present invention. In the depicted embodiment,network 200 includes a firstdata processing system 202 that is directly connected (connected without an intervening system or box) to a seconddata processing system 204 byconfigurable cable 210.Configurable cable 210 includes acoupling piece 212 that is alterable between at least a first configuration and a second configuration. - As depicted in greater detail in FIG. 3A,
configurable cable 210 andcoupling piece 212 are connected in a crossover configuration suitable for use in a direct connect Ethernet network. In this embodiment,configurable cable 210 includes eight signal wires typically arranged as 4 twisted pairs. The eight signals include plus and minus transmit signals (T+, T−) and plus and minus receive signals (R+, R−). In the direct connect configuration, also referred to as the crossover configuration denoted by the “C” incoupling piece 212, the T+/− signals of the first device are connected to the R+/− signals of the second device and vice versa. - More specifically,
configurable cable 210 includes a set ofsignal wires 211 each connected at a first end to afirst connector 213 and each connected at a second end tosecond connector 215. In one embodiment, first andsecond connectors cable 210 connects a first subset of its signal wires to like pins of the two connectors and a second subset of its signal wires to unlike pins. Specifically, the first set of signals wires includes the signal wires connected topins pins - The crossover configuration of FIG. 3A beneficially enables two data processing systems to communicate with each other over physical medium connected between the two devices without any intervening connection device or box such as a router, hub, and so forth. Although the direct connect system has limitations, it represents a low cost option for sharing resources between two separate systems.
- Referring now to FIGS. 2B and 3B, a
data processing network 220 employingconfigurable cable 212 is illustrated. As depicted in FIG. 2B,network 220 includes a firstdata processing system 202, a seconddata processing system 204, and ahub 214.Hub 214 includesmultiple ports 217 each of which may be used to connect to a data processing system. In this configuration,data processing systems hub 214 via a correspondingconfigurable cable 210. In this hub configuration, thecoupling piece 212 of eachconfigurable cable 210 is set to the pass through configuration setting denoted by the “P” withincoupling piece 212. As suggested by its name, the pass through configuration (shown in FIG. 3B) is a configuration in which each of thesignal wires 211 is connected between a like pair of connector pins. In other words, pin 1 offirst connector 213 is connected to pin 1 ofsecond connector 215,pin 2 ofconnector 213 is connected to pin 2 ofsecond connector 215, and so forth. The hub configuration of FIG. 2B is useful for connecting multiple (more than two) systems in a single network via a common hardware component. In an Ethernet compliant network,hub 214 is configured to receive signals from its systems in the pass through configuration. -
Configurable cable 210 according to the present invention is designed to be easily altered from a first configuration such as the crossover configuration of FIG. 3A to a second configuration such as the passthrough configuration of FIG. 3B. The alternation of the cable's configuration may be achieved manually or electrically. Preferably, the cable's configuration may be altered from the first to the second configuration and back without the use of tools and or other external equipment. - Referring now to FIGS. 4A and 4B, a cylindrical in-line embodiment of
configurable cable 210 andcoupling piece 212 is depicted where FIG. 4B is a cross-sectional view of thecoupling piece 212 of FIG. 4A. In this embodiment,configurable cable 210 includes a first set ofsignal wires 211A connected tofirst connector 213 and asheathing 230 that encloses the signal wires.Cable 210 further includes a second set ofsignal wires 211B connected tosecond connector 215. Couplingpiece 212 connects to the first set ofsignal wires 211A and the second set ofsignal wires 211B. Couplingpiece 212 controls the routing between first andsecond signals wires coupling piece 212 is substantially cylindrical in shape as is thecable sheathing 230. The diameter ofcoupling piece 212 may be equal to or somewhat greater than the diameter ofsheathing 230. - As shown in the cross sectional view of FIG. 4B, the depicted embodiment of

In the RJ45 Ethernet embodiment, for example, the signal wires that would connect toconductive conduits 241 would includesignals - The annular
outer ring 242 includes at least two sets of conductive conduits. A first set ofconduits 244 serve as the active conduits whenannular ring 242 is in a first position relative toinner piece 240 while the second set ofconduits 246 serve as the active conduits when the annularouter ring 242 is in a second position relative toinner piece 240. When the annularouter ring 242 is in the first position relative toinner piece 240 the first set ofconduits 244 connect the pins of the configurable cable's first connector to the pins of the cable's second connector in a first configuration.
